Struct getopts::Matches [−][src]
The result of checking command line arguments. Contains a vector of matches and a vector of free strings.
Fields
free: Vec<String>
Free string fragments
Methods
impl Matches[src]
impl Matchespub fn opt_defined(&self, nm: &str) -> bool[src]
pub fn opt_defined(&self, nm: &str) -> boolReturns true if an option was defined
pub fn opt_present(&self, nm: &str) -> bool[src]
pub fn opt_present(&self, nm: &str) -> boolReturns true if an option was matched.
pub fn opt_count(&self, nm: &str) -> usize[src]
pub fn opt_count(&self, nm: &str) -> usizeReturns the number of times an option was matched.
pub fn opts_present(&self, names: &[String]) -> bool[src]
pub fn opts_present(&self, names: &[String]) -> boolReturns true if any of several options were matched.
pub fn opts_str(&self, names: &[String]) -> Option<String>[src]
pub fn opts_str(&self, names: &[String]) -> Option<String>Returns the string argument supplied to one of several matching options or None.
pub fn opt_strs(&self, nm: &str) -> Vec<String>[src]
pub fn opt_strs(&self, nm: &str) -> Vec<String>Returns a vector of the arguments provided to all matches of the given option.
Used when an option accepts multiple values.
pub fn opt_str(&self, nm: &str) -> Option<String>[src]
pub fn opt_str(&self, nm: &str) -> Option<String>Returns the string argument supplied to a matching option or None.
pub fn opt_default(&self, nm: &str, def: &str) -> Option<String>[src]
pub fn opt_default(&self, nm: &str, def: &str) -> Option<String>Returns the matching string, a default, or None.
Returns None if the option was not present, def if the option was
present but no argument was provided, and the argument if the option was
present and an argument was provided.
pub fn opt_get<T>(&self, nm: &str) -> Result<Option<T>, T::Err> where
T: FromStr, [src]
pub fn opt_get<T>(&self, nm: &str) -> Result<Option<T>, T::Err> where
T: FromStr, Returns some matching value or None.
Similar to opt_str, also converts matching argument using FromStr.
pub fn opt_get_default<T>(&self, nm: &str, def: T) -> Result<T, T::Err> where
T: FromStr, [src]
pub fn opt_get_default<T>(&self, nm: &str, def: T) -> Result<T, T::Err> where
T: FromStr, Returns a matching value or default.
Similar to opt_default, except the two differences.
Instead of returning None when argument was not present, return def.
Instead of returning &str return type T, parsed using str::parse().
